I enjoyed it quite a bit. I thought the characters were really interesting, the plot was engaging, and at some point I would like to read the other books. However, it was rather disturbing, but well done because it wasn't too graphic. There was enough information there about the rapes and murders for the reader to understand and get a picture of what was happening without the author describing so much that the reader gets too disgusted to continue.
Really, I think Men Who Hate Women pretty much nails what this book about. It was almost a little overpowering how much misogyny there is in this book and just how unapologetic those men are about it. Also, in the book, other than Salander's guardian, it was condensed to one family, which made it even worse, in my opinion. But I don't know if this book would have hit it off so well over here if they'd kept the original title. I honestly had no idea what this book was about when you guys decided on it and, well, it was kind of a slap to the face once I got to chapter 11.
I'm still kind of letting the ending sink in, so I'll post some more later.
